About

The original idea for Locust was Carl Byström's who made a first proof of concept in June 2010. Jonatan Heyman picked up Locust in January 2011, implemented the current concept of Locust classes and made it work distributed across multiple machines.

Jonatan, Carl and Joakim Hamrén has continued the development of Locust at their job, ESN Social Software, who have adopted Locust as an inhouse Open Source project.
